		The <b>BOOST_PP_LIST_FOR_EACH_PRODUCT</b> macro repeats a macro for each cartesian product of several <i>lists</i>.
	</div>
	<h4>Usage</h4>
		<div class="code">
			<b>BOOST_PP_LIST_FOR_EACH_PRODUCT</b>(<i>macro</i>, <i>size</i>, <i>tuple</i>)
		</div>
	<h4>Arguments</h4>
		<dl>
			<dt>macro</dt>
			<dd>
				The binary macro of the form <i>macro</i>(<i>r</i>, <i>product</i>).&nbsp;
				This macro is expanded by <b>BOOST_PP_FOR_EACH_PRODUCT</b> with each cartesian product in <i>tuple</i>.&nbsp;
				It is expanded with the next available <b>BOOST_PP_FOR</b> repetition and a <i>tuple</i> containing a cartesian product.&nbsp;
				This <i>tuple</i> will have <i>size</i> elements.
			</dd>
			<dt>size</dt>
			<dd>
				The size of <i>tuple</i>.
			</dd>
			<dt>tuple</dt>
			<dd>
				A <i>tuple</i> of <i>lists</i> from which cartesian products are obtained.
			</dd>
		</dl>
	<h4>Remarks</h4>
		<div>
			This macro is a repetition construct.&nbsp;
			If two <i>lists</i> are (<i>a</i>, (<i>b</i>, (<i>c</i>, <b>BOOST_PP_NIL</b>))) and (<i>x</i>, (<i>y</i>, (<i>z</i>, <b>BOOST_PP_NIL</b>))),
			this macro will produce the following sequence:
			<div>
				<i>macro</i>(<i>r</i>, (<i>a</i>, <i>x</i>))
				<i>macro</i>(<i>r</i>, (<i>a</i>, <i>y</i>))
				<i>macro</i>(<i>r</i>, (<i>a</i>, <i>z</i>))<br>
				<i>macro</i>(<i>r</i>, (<i>b</i>, <i>x</i>))
				<i>macro</i>(<i>r</i>, (<i>b</i>, <i>y</i>))
				<i>macro</i>(<i>r</i>, (<i>b</i>, <i>z</i>))<br>
				<i>macro</i>(<i>r</i>, (<i>c</i>, <i>x</i>))
				<i>macro</i>(<i>r</i>, (<i>c</i>, <i>y</i>))
				<i>macro</i>(<i>r</i>, (<i>c</i>, <i>z</i>))
			</div>
		</div>
		<div>
			Previously, this macro could not be used inside <b>BOOST_PP_FOR</b>.&nbsp;
			There is no longer any such restriction.&nbsp;
			It is more efficient, however, to use <b>BOOST_PP_LIST_FOR_EACH_PRODUCT_R</b> in such a situation.
